Samantha
used a number of motions or gestures to do magic. The “Nose Twitch”
was the best known and most frequently used, but there were others.
In # 1, Samantha used a combination
of a nose twitch, finger waving, and an incantation to get rid of Endora.
All it got her was the reprimand: “Why you naughty little witch.”

This was
the only time she used such a combination of actions to do magic. Everything
that followed was simpler.

NOSE TWITCH

Actually, she moved her upper lip back and forth, but it was
called a nose twitch, and was the most common of her magic motions. (#
251)

The twitch always started with a lip motion to the right, and
varied in length from situation to situation. (# 140)

On occasions where someone was near that Samantha did not want
to see her twitch, she put her hand up to shield her nose from sight.
